How to choose Motor and Propeller for Quadcopter and Multicopter You won’t believe how much maths and aerodynamics are involved when the engineers are designing the propellers and motors. Therefore you know how difficult it is to choose the best motor and propeller combination for your quadcopter for best performance. Fortunately this is not a new subject, and there are so many people shared their experience about this. As part of the quadcopter tutorial I will share some information for beginners about how to choose motor and propeller for quadcopter, which also applies to other types of multicopter. Here is a guide about the types prop adapters for your motors, and the pros and cons you might be interested. When selecting motors, there usually are specification that comes with the motor either provided by the seller or manufacturer. To choose a motor we first need to how much weight you are planning to take, and then to work out the thrust required to lift the quadcopter. A rule of thumb is Required Thrust per motor = ( Weight x 2 ) / 4

Flyduino Mega , a Multiwii/Ardupirates/Aeroquad based aerial video platform FC Discussion Flyduino Mega , a Multiwii/Ardupirates/Aeroquad based aerial video platform FC The Flyduino, is avaiable at Most actual shematic for the Flyduino! Pinout for Multiwii showen here (many thanks Alex): Based on the fantastic work of Alex and Oleg. With a Arduino Pro, you can only drive a quad and a regular receiver. Org WMP and BMA020 on 100hz FFIMU on 400HZ Oleg made a quick drawing for the Thanks to Hogster a shematic for the Flyduino 1.1 this shows the serial change for Flyduino V 2.0 A redesigned Arduino Mega, which suits more our needs. -I brought out all PWM which are avaiable for Octos, Servos, whatever. -All serials (2 have pinheaders, one have a JST Connector) are brought out for GPS, LCD, wireless Data. -Analog In 8-15 are for remote controller with a 3 row pinheader. its proved see the kinderkram post

Interfacing 2.4G RC transmitter to Arduino Today you can buy complete quadcopter of helicopter kit for as low as $50. They are made to be used right away as there are all you need including batteries, chargers, transmitter and other means. But like always these cheap models don’t last long. And so the rest of stuff you get. Usually transmitter is locked to model and cannot be reused on different types. With a bit of coding he was able to detect if all necessary control positions like throttle, yaw, pitch and roll with all trims. Read

Connecting elements « MultiWii Dimensions of the Wii Motion Plus are quite similar to Arduino Pro Mini card’s one. This is useful for designing a small and homogeneous card. The 2 PCBs are simply connected by four wires. Wii Motion Plus extension is powered by the regulated 5V of the Arduino Pro Mini. The analog inputs A4 and A5 are connected via the I2C pins SDA and SCL. (the photo describes the old way to power WMP via VCC and not PIN 12) Note that it is not mandatory to use a Nunchuk to operate the Multicopter described in this article.It is mandatory only if you want to have an autolevel feature. The software recognizes automatically the presence of a nunchuk connected. Only 4 wires need to be connected between the WMP and the NK. MultiWii can now handle many more sensors than just the WMP or NK. It’ possible to upgrade a basic setup by adding some sensors with breakout boards (Sparkfun has multiple references) Or it’s possible to buy a complete sensor IMU to connect to an Arduino. Some Arduino board example:

Build Your Own Drone First Person View The First Person View or FPV section of BYOD offers the best selection of hand-picked products from Fat Shark and ImmersionRC, the world leaders in First Person View technology, DJI Innovations the flight control experts and 3D Robotics from the open source community. The two worlds of FPV and UAV / Drones have come together over a very short period of time, First Person View or FPV flights were once a type of remote-control (RC) flying that started out in the world of RC planes which involved mounting a small video camera and transmitter to an RC aircraft to send down a live video link of the flight in real time, the pilot would use Fat Shark Attitude V2 goggles or a portable LCD screen to see and fly from the aircraft as if they were on board the RC plane. If you are looking to use you current aircraft or just starting out into the RC world with either a plane or a multi rotor aircraft for fun or professional flights we will have a system that will meet your requirements.

Curved Fuselage Panels From Foam Poster Board | Flite Test Hi Guys, This is the article I mentioned about making curved panels with foam poster board. I am still working out methods but this is what I have so far. The first attempts at making curved panels were just working with a couple of scraps: I scored the backs with a fingernail and then hand formed the curves. Let's see if this works for real,,, I have made my first attempts on an actual project here. The first piece was the one with double curved sections and a flat piece between that was to fit between the rudders. Next I removed the paper backing on the two outer sections and made knife scores about 1/8" apart along the lines of the bend. Scoring. Hand forming is easy with the score cuts. The edges were back-cut and sanded smooth. The end result with rear notches like the real thing. A similar method was used for the one piece front fuselage panel. Notice that the front edge of the flat part behind the slot rests on top of the blue foam to help establish the shape. Happy building! Update:

Arduino Multiwii Quadcopter Connection Test Today I loaded up the Arduino Multiwii Quadcopter code on the Arduino Uno, and connected everything including a Radio controller, the IMU, ESC and motors, it works straight away! It’s so much easier than I thought. The reason I am using the Arduino as a flight controller was my KK2.0 was totally damaged in the last crash. Luckily everything else apart from the flight controller and frame is fine! So I decided rather than buying a new flight controller, I might try to dig out a spare Arduino board to make one myself. I basically followed this diagram from the Arduino Multiwii website to connect everything. Here is the result. The motors are controlled correctly, and also response to the IMU as well! For the start, I might just use Multiwii software, later on I might try writing one myself. If you find this article useful. To help us maintain and improve this website.

RCTimer/Turnigy/Hobbywing ESC DIY Firmware Flashing Thanks to the help of timecop (yes he can be nice as long as he is interested ) I managed to flash my RCTimer 10A and 30A ESC. The procedure should be the exact same for the 18A and 20A versions. Also note that the procedure is most likely the same for the Turnigy Plush if they have the same chip and pads. Another note. timecop and I also had some RCT 10A that went poof after the reflash. 1- Required stuff: - RCTimer or other Atmel chip compatible ESC stripped of it's shrink tube. Check this list made by TomSn0w of all compatible ESCs with their specs and appropriate firmware file. - An AVR USB programmer. - The hex file for the firmware (.hex is the compiled firmware, you can compile your own if you want to as well): 1- Go there: 2- Hit the download button on the top right 3- Right click and save as the tgy.hex file from the bottom on the popup. - AVRDUDE or AVRStudio or what ever software you want to use to actually flash the firmware. 2- Step by Step: eRC 45A:

One Sheet and Two Sheet No-Waste Flying Wings | Flite Test Hello again out there... Some people would say I dont have a life, always off by myself playing with airplanes. But I say "That is a pretty good life". Anyone else out there feel that way? Anyway, here is what I am playing with now. I thought it would be interesting to try to design a foam plane that was made with one full sheet, no other foam board and no scrap. The span is 40". One thing I am not sure about. This is the prototype. I fell short of my no scrap / no extra foam goal in a couple of places. Here are some other pix: One wing made. Bat or stingray nose. The business end. The wing halves were joined without any trimming of factory edges, The way it came together with the camber gave about 1/2" of dihedral. A better picture of the "plans ". Well that is it. If anyone has experience with under camber on a flying wing please drop me a line. Update: I have also put together a two sheet no-waste version. It has a 60" wing span. I think the tail fins are bigger than what is needed. Up:
